IMPROVEMENT IN VENTILATING AND HEATING FURNACES.

Specification forming part of Letters Patent N 0. 170,615, dated November 30, 187 5; application filed September 9, 1875.

To all whom it may concern:

Be it known that I, JOHN A. YOUNG, of the city and county of St. Louis, and State of Missouri, have invented a new and useful Improvement in Ventilating and Heating Furnaces, of which the following is a specification My improvement relates toa combined arrangement of chambers and pipes, so attached to a furnace as to draw the vitiated air from the room and supply it with warm pure air. It-consists, furthermore, in arranging the pipes and chambers so that the air in a room may be taken to the furnace, heated, and returned to the apartment.

The furnace proper is partly or wholly surrounded by a chamber communicating at the lower part with the outer air, and at the upper part with the room or rooms to be heated. This chamber is surrounded or partly surrounded by another air-chamber connected at bottom with the lower part of the room orrooms, and its upper part connected with the chimney, so that the heat escaping from the airheating chamber is availed to carry the foul air from the lower part of the rooms into the chimney. The partition between the two airchambers has a damper, allowingthe two chambers to be made to communicate at their lower part, and the pipe leading from the outer or foul-air chamber has a damper, by which it may be closed, so that when the former damp er is open, and the latter closed, the air may pass from the bottom of the room or rooms to the air-heating chamber, and return from said chamber to the rooms. In such case the Outer air-supply pipe is closed with a damper.

In the drawings, Figure 1 is a view of the furnace, one-half in elevation, and one-half in axial section at a a, Fig. 2. Fig. 2 is a horizontal section at b b, Fig; 1. Fig. 3 is aview of the furnace, one-half in elevation, and onehalf in section at c c, Fig. 2. Fig. 4 is a horizontal section at d d, Fig. 1 Fig. 5 showing the house-walls in section and the furnace in elevation, and illustrating the course of the air-pipes.

at the upper part all around and abovethe tire-chamber,and at the lower portion partway around the ash-pit. H is an air-supply pipe to the chamber G, the pipe being furnished with a damper, I, with which it may be partly or wholly closed. J is the pipe through which the heated air escapes from chamber G, and when there are several rooms in the house there would be a pipe leading to the upper part of each room. K is a chamber extending partly or wholly around the chamber G, so that it will be heated by the heat given out from the outer wall of chamber G. The chamber K receives its air-supply from the ,lower part of the room L through a pipe or pipes, M, extending from the lower part of the room to the lower part of the ventilating-chamber K, and the air escapes from the chamber K through a pipe, N, which discharges into the chimney F. This pipe has a damper, O, by which it may be closed. The outer wall, the intermediate wall, and the inner wall are shown respectively at I, Q, and

R. S is an annular casting between the walls Q, and R, which has orifices S for the passage of air through it. This casting gives support to the fire basket or grate. T is an aperture in the lower part of the wall Q, and this aperture is closed by a damper, U, moved by a handle, V, extending through the outer wall or case 1?.

The operation is as follows: The damper U being closed, and those I and 0 being open, the air enters, through pipe .H, is heated in chamber Gr, and passes upward through pipe or pipes J, which discharge into the upper parts of the room. Thefoulair escapes through pipe M, and its motion is accelerated by he coming heated in chamber K, and by the upward draft in the chimney, the discharge-pipe N being in communication with the chimney F. When the rooms are not occupied, and the air is not vitiated as warming up the building at night or in the morning, the dampersIand 0 may be closed, and damper U opened, in which case the air taken from the room through pipe M passes directly into.

chamber G, andis returned to the room through pipe J.

In Fig. 3 is illustrated the furnace as on a level with a room to be heated. In Figs. 1 and 5 the furnace is shown below the level of the rooms to be heated.

I have described the heated air as entering the rooms near the ceiling, and the foul air as passing oft near the floor, and this is my preferred arrangement; but, if desired, the heated air from the chamber G may enterthe warm pure air in the upper part of the room.

The outer shell P is shown as of metal; but it may be built up of brick or any other suitable material.

I have shown how this ventilating-chamber K, with its pipes M and N, may be applied to one particular kind of furnace; but this improvement is applicable to heating-furnaces of all descriptions. i

I claim as my inventioui p p l. The foulair chamber K, surrounding wholly or in part the warm-air chamber G and fire'chamber O, with its pipes M and N, in combination with the pipes H and J, substantially as and for thepurposes set forth.

2. The combination of chambers G and K, air-pipesH J M N, and dampers I O U with a furnace, E R, substantially as set forth.
